How to Cite an Image
Usually, it is not enough to simply cite the website where you got the image. You must give credit to the person who created it, as far
For government website images, usually the name of the government agency is all that is available.
For Flickr and other photo-sharing sites, you should find the name of the person who uploaded the image. Some users give their real names (which can be found on their profile), but others don't. Use the real name if it is available and the username if it is not.
On Wikimedia, you are provided a description page with a large thumbnail of the image, followed by source information. Again, some users give their real names and others don't.
In your citation, you should also give the "permission." Examples:
"(C) Copyright (copyright owner). Used by written permission" for a copyrighted image that you got permission to use
"(CC) Some rights reserved" for an image with a Creative Commons license
"License: GFDL/GPL/etc." for an image with another type of free license
Optional: "Public domain" for a public domain image
Finally, it is best to give the URL of the exact location where you found the image. On paper, list the URL starting with http:// — but for web pages, you can use a hyperlink. This is optional for public domain images.
Put the above information into the format requested by your instructor.
